The games currently featured in the promotion are Mass Effect 2, Battlefield: Heroes, Battlefield: Bad Company 2, The Sims 3 and Spore, with "others to be announced throughout the year"--which Dr Pepper reveals will include Skate 3 and Medal of Honor.

A few details from EA on the DLC revealed so far are quoted below.

Game enhancements for The Sims 3, for example, feature theme-based bundles including Vintage Vegas, Beach Party, Celebrity and Football. Consumers will be able to download exciting new content ranging from a party top or hot boots all the way to a cool Retro car. Fans who have played The Sims over the years will recognize items inspired by previous The Sims games like the Lips Couch or Boomerang Window.

Other examples of exclusive downloadable content include the following:

In Spore, a dozen Cyborg-themed body parts - such as eyes, heads and arms - can be redeemed and used in the Spore Creature Creator. These parts allow players to mix robot and organic creature body parts to design their own Cyborg creatures. The exclusive Cyborg parts will be usable by all owners of the Spore PC game and anyone who downloads the free Spore Creature Creator Trial Edition...

In Mass Effect 2... there are three unique pieces of armor: two helmets and a visor...

In Battlefield Heroes, there are four sets of unique character clothing, and consumers get a pair of outfits per download, one for each side.

In Battlefield: Bad Company 2 four kit upgrades allow you to become a unique Special Activities soldier, with new camouflage and a modified weapon. Kit upgrades also contain new awards and an additional achievement.
